The results show that the temperature of the alloy gradually decreases from the casting mouth to the exit in the roll-shoe gap, and the isothermal line deviates from the shoe side to the roll side.

结果表明：辊靴型腔内合金的温度从入口至出口逐渐降低，合金等温线向工作辊偏移；随着浇注温度的降低，辊靴型腔内半固态区间逐渐增大；为了获得优良的半固态金属浆料，确定浇注温度为710~770 ℃；合金在辊靴型腔内层流运动时，越靠近工作辊内表面，合金的运动速度越快；随着挤压模具扩展角的增大，挤压模具出口型材宽度上中心与两侧边部合金的温度差减小；半固态合金进入模具后呈辐射状逐层向前推进填充模具扩展腔，最后再逐渐向模具出口合拢；为了改善模腔内金属流动速度的不均匀性，扩展角以45为宜。

And the final result of this kind of gambling is thegeneration of related international coordination and the restraint mechanism such as The Arrangement on Guidelines for Officially Supported Export Credits'(hereinafter referred to as Gentlemen's Agreement) in which very definite limitationhas been put on the policy tools like interest rate, premium which are the key factors to determine the effect of ECAs.
